Answer» Answer: Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe ACUTE Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. Coronaviruses are zoonotic, meaning they are TRANSMITTED between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans. Common signs of infection include respiratory symptoms, fever, COUGH, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, KIDNEY failure and EVEN death. Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.

24.	7. Rakesh lent out Rs 2000 for 5 years at 15% per annum and borrowed Rs 8000 for 3 years12% per annum. How much did he gain or lose?
Answer» Step-by-step explanation: Considering it is simple INTEREST. If he lent out 2000 for 5 YEARS at rate of 15% per annum we need to find how much profit he has made. Simple interest formula is A=(P×R×T)÷100 P=2000 R=15% T=5 years hence it is 2000×15×5/100=1500 this is profit now to find out how much interest he had to pay when he borrowed 8000 at the rate of 12% per annum. P=8000 R=12% T=3 years hence it is 8000×12×3/100=2880. this is loss since he had to give this money. total profit= profit - loss = 1500-2880= -1380. Since profit is in negative it means that there was a loss of 1380 rupees.

7. Rakesh lent out Rs 2000 for 5 years at 15% per annum and borrowed Rs 8000 for 3 years12% per annum. How much did he gain or lose?

Answer»

Step-by-step explanation:

Considering it is simple INTEREST. If he lent out 2000 for 5 YEARS at rate of 15% per annum we need to find how much profit he has made.

Simple interest formula is A=(P×R×T)÷100

P=2000

R=15%

T=5 years

hence it is 2000×15×5/100=1500 this is profit

now to find out how much interest he had to pay when he borrowed 8000 at the rate of 12% per annum.

P=8000

R=12%

T=3 years

hence it is 8000×12×3/100=2880. this is loss since he had to give this money.

total profit= profit - loss = 1500-2880= -1380.

Since profit is in negative it means that there was a loss of 1380 rupees.

Answer» ANSWER: LET the current age of Rahul and Haroon be 5X and 7X respectively Four years later their ages become 5x + 4 and 7x + 4 respectively. According to the question, 5x + 4 +7x + 4 = 56 or 12x + 8 = 56 Transposing 8 to the RHS we get, 12x = 48 Dividing both sides by 12 gives, x = 48/12 = 4 Thus current age of Rahul = 54 = 20 Haroon = 74 = 28

29.

The ages of Rahul and Haroon are in the ratio 5:7. Four years later the sum of their ages will be 56 years. What are they present ages ?✔Give verified answer✔

Answer»

ANSWER:

LET the current age of Rahul and Haroon be 5X and 7X respectively

Four years later their ages become 5x + 4 and 7x + 4 respectively.

According to the question,

5x + 4 +7x + 4 = 56

or 12x + 8 = 56

Transposing 8 to the RHS we get,

12x = 48

Dividing both sides by 12 gives,

x = 48/12 = 4

Thus current age of Rahul = 5*4 = 20

Haroon = 7*4 = 28

Understand what you are asked to find.

2. Translate the problem to an equation.

Assign a variable (or VARIABLES) to represent the unknown.

Clearly state what the variable represents.

X A number consists of two digits of which ten’sdigit exceeds the unit digit by 7. The numberitself is equal to 10 times the sum of its digits.Find the number.

Answer»

Step-by-step EXPLANATION:

Let the DIGIT in the tens place be x and units place be y.

FINAL number = 10x + y

x = y + 7

x - y = 7 ----- (1)

10x + y = 10(x + y)

10x + y = 10x + 10y

10x - 10x = 10y - y

9y = 0

y=0 ------(2)

Substituting (2) in (1)

x - 0 = 7

x = 7

Final number = 10x + y = 10(7) + 0 = 70

Answer» Answer: In physics, a force is any INTERACTION that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can ALSO be described intuitively as a push or a pull. A force has both magnitude and DIRECTION, making it a VECTOR QUANTITY.

Find the ratio of two different sector of a circle with radius 20 cm and angles respectively 15 and 90.

Answer»

$\large\underline{\sf{Solution-}}$

DIMENSIONS of first SECTOR :-

$\begin{gathered}\begin{gathered}\bf \:Given-\begin{cases} &\sf{radius,r_1 = 20 \: cm} \\ &\sf{<klux>ANGLE</klux>,\theta_1 \: = 90 \degree} \end{cases}\end{gathered}\end{gathered}$

We know,

Area of sector is

$\boxed{ \sf \: Area_{(sector)} = \pi \: {r}^{2} \dfrac{\theta}{360\degree}}$

where,

r is the radius of sector

θ is central angle or sector angle.

So, on substituting the values of r and θ, we get

$\rm :\longmapsto\:Area_{(sector1)} = \pi \: {(20)}^{2} \dfrac{90\degree}{360\degree}$

$\bf\implies \:Area_{(sector1)} = 100 \: \pi \: {cm}^{2} - - - (1)$

Now,

Dimensions of SECOND sector :-

$\begin{gathered}\begin{gathered}\bf \:Given-\begin{cases} &\sf{radius,r_2 = 20 \: cm} \\ &\sf{angle,\theta_2 \: = 15 \degree} \end{cases}\end{gathered}\end{gathered}$

So, again on substituting the values of r and θ, we get

$\rm :\longmapsto\:Area_{(sector2)} = \pi \: {(20)}^{2} \dfrac{15\degree}{360\degree}$

$\bf\implies \:Area_{(sector2)} = \dfrac{50\pi}{3}\:{cm}^{2} - - - (2)$

Therefore,

$\rm :\longmapsto\:\dfrac{Area_{(sector1)}}{Area_{(sector2)}} = \dfrac{100\pi}{\dfrac{50\pi}{3} }$

$\rm :\longmapsto\:\dfrac{Area_{(sector1)}}{Area_{(sector2)}} = 6$

$\bf\implies \:Area_{(sector1)}: Area_{(sector2)} = 6 : 1$

─━─━─━─━─━─━─━─━─━─━─━─━─

Additional Information :-

$\boxed{ \sf \: Length \: of \: arc_{(sector)} = 2\pi \: r \: \dfrac{\theta}{360\degree}}$

$\boxed{ \sf \: Perimeter_{(sector)} = 2r + l}$

$\boxed{ \sf \: Area_{(major \: sector)} = \pi \: {r}^{2} \dfrac{(360\degree - \theta)}{360\degree}}$

$\boxed{ \sf \: Area_{(minor \: segment)} = \bigg[\pi \: {r}^{2} \dfrac{\theta}{360\degree} - \dfrac{1}{2} {r}^{2}sin\theta\bigg]}$

ANSWER:

Let the first discount be x %

Selling price = 108

Thus, price after first discount = \frac{100-x}{100}\times 180

Price after second discount, as there is successive discount, the second discount must be applicable to the REDUCED price, so,
